Sarens Lifts the Main Sections of the Puteaux Footbridge in Paris

Sarens lifts the 460T of the Puteaux footbridge in Paris
on the eve of the New Year

January 2019:Sarens was
commissioned by Viry, a metal construction company, known for its
complex architectural works closely associating steel and glass, to
transport and erect the main section of the Puteaux footbridge in
Paris. The footbridge will allow the commuters to walk to the
island of Puteaux by crossing the Seine and the 2x3 tracks of the
RD7.

The bridge was assembled on the port of Gennevilliers and had to
be transported by river to the site and installed. Sarens crew
decided to deploy:

Two CC3800

CS1000

Barge Karel and Viktor

The equipment was mostly available in France, the barge was
transported from Limay. It took the team around a week to mobilise
and assemble the equipment on site.

The first section of the pedestrian bridge linking the Dion
Bouton wharf to the island of Puteaux was successfully laid on the
night of December 14, 2018 while the second main section was
installed on the evening of 31st December, 2018. The two
sections weighing 100T and 330T were lifted in tandem at 40m and
23m respectively. The crane crawled by 25m and then slewed to
install the bridge section.

According to our project Engineer, Tomas Spinnoy, "While we
carried out the transport of the bridge sections by river we had to
carefully move them under the bridges on the Seine which were of
low height. The ground was muddy at site and balancing the cranes
was a challenge which our skilled teams executed successfully and
safely, making the bridge available for pedestrians on the New
Year."
